Leukocyte Telomere Length (LTL, kb) in Three Surveys (S1, S2, and S3)

	Whites		African Americans		p for race difference
	Males (n = 73)	Females (n = 131)	Males (n = 19)	Females (n = 48)	Males	Females
	Mean (SD)	Mean (SD)	Mean (SD)	Mean (SD)	Males	Females
LTL at S1	7.005 (0.617)	7.114 (0.699)	7.713 (0.656)	7.650 (0.732)	<0.001	<0.001
LTL at S2	6.844 (0.645)	6.938 (0.711)	7.525 (0.688)	7.450 (0.769)	<0.001	<0.001
LTL at S3	6.612 (0.582)	6.749 (0.711)	7.196 (0.634)	7.215 (0.792)	<0.001	<0.001

Note: Testing performed using a t test assuming equal variances. No significance sex differences within race were found. SD = standard deviation.
